Set your oven to 350°F (175°C) and prepare a loaf pan by lining it with parchment paper or greasing it thoroughly.
In a large mixing bowl, beat together the eggs, Greek yogurt, and melted butter or coconut oil until fully blended and creamy.
Incorporate the baking powder, salt, and your choice of xanthan gum or psyllium husk powder into the wet mix. If you’re using almond flour, fold it in now. Stir everything until you achieve a thick and uniform batter.
Transfer the batter into the loaf pan, smoothing the surface with a spatula to create an even top.
Bake the loaf in the oven for about 35 to 45 minutes, until the crust turns golden brown and a toothpick inserted at the center comes out clean.
Allow the bread to sit in the pan for 10 minutes to cool down before moving it to a wire rack. Let it cool entirely before cutting to maintain its structure and avoid crumbling.
